What are the characteristics of the perfect LED underwater fishing light?
Is color important? This is a serious problem, and fishing enthusiasts and fishermen have long been searching for their secrets. Some anglers and fishermen think that the choice of color is crucial, while others say it doesn't matter. Scientifically, there is evidence that both views may be correct. There is ample evidence that choosing the right color can improve the chances of attracting fish when the environmental conditions are right, but science can also show that in other cases, the value of color is limited and not as important as imagined. The fish was born more than 450 million years and is a very good creature. For thousands of years, they have made many superb adaptive adjustments in the marine environment. The world that lives in the water is not easy, there are high environmental opportunities and serious challenges. For example, the sound is five times faster in the water than in the air, and the water is much better. The ocean is actually a very noisy place. By having good auditory perception, using their inner and lateral lines to detect prey or avoid enemies, fish can take advantage of this. The water also contains unique compounds that fish use to identify other members of their species, find food during the breeding season, detect predators and perform other functions. Fish has developed a remarkable sense of smell and is considered to be a million times better than humans. However, water is a serious challenge for fish and fishermen for vision and color. Many of the characteristics of light change rapidly with water flow and depth. What does the attenuation of light bring? The light that humans see is only a small fraction of the total electromagnetic radiation received from the sun, that is, we see the so-called visible spectrum. The actual color in the visible spectrum is determined by the wavelength of the light: the longer wavelengths are red and orange; the shorter wavelengths are green, blue and purple. However, many fish can see the colors we don't have, including UV rays. Ultraviolet light travels farther in the water than most of us can imagine. When light enters the water, its intensity drops rapidly and the color changes. These changes are called attenuation. Attenuation is the result of two processes: scattering and absorption. Light scattering is caused by particles or other small objects suspended in water - the more particles, the more scattering. The scattering of light in water is somewhat similar to the effects of smoke or fog in the atmosphere. Due to river input, coastal water bodies usually have more suspended matter, agitating the material from the bottom and increasing plankton. Due to this larger amount of suspended matter, light typically penetrates to a lesser depth. In relatively clear offshore waters, light penetrates deeper into the depths. Light absorption is caused by several substances, such as light being converted to heat or used in chemical reactions such as photosynthesis. The most important aspect of fishing is the effect of water itself on the absorption of light. For different wavelengths of light, the amount of absorption is different; in other words, the various colors are absorbed differently. Longer wavelengths, such as red and orange, are quickly absorbed and penetrate to a much shallower depth of the shorter blue and purple wavelengths. Absorption also limits the distance that light enters the water. About three meters (about 10 feet), about 60% of total light (sunlight or moonlight), almost all red light will be absorbed. At 10 meters (about 33 feet), about 85% of the total light and all the red, orange and yellow light have been absorbed. This will seriously affect the effect of the angler's bait. At a depth of three meters, red turns into ice and appears gray. As the depth increases, it eventually turns black. As the depth increases, as all other colors are absorbed, the now dimmed light turns blue and eventually turns black. The absorption or filtering of color also works in the horizontal direction. So again, a red flight that is only a few feet away from the fish seems to be gray. Again, other colors change with distance. For the color to be seen, it must be hit by the same color of light and then reflected in the direction of the fish. If the water has attenuated or filtered out a color, the color will be gray or black. Due to the large depth of UV light penetration, the fluorescence generated under ultraviolet radiation is an important part of the underwater rich environment. What is the best color for light-sucking fish? Scientists really don't know what fish to see, in other words, what images reach their brains. Most studies of fish vision are performed by physical or chemical examination of different parts of the eye, or by determining how the fish in the laboratory react to various images or stimuli. It may not be scientific to conclude that the fish's visual ability is highly consistent and deterministic through the fact that different species may have different visual capabilities and that laboratory results may not represent what is happening in the real world of oceans, lakes or rivers. Physical studies of the eye and retina have shown that most people can obtain sharply focused images, detect motion, and have good contrast detection capabilities. And there are plenty of experiments that show that the minimum level of light is needed before the fish can recognize the color. As the research progresses, different fish have a particular color.
